b. THREADED PIPE
(1) Apply pipe joint compound to all outside pipe
threads.
(2) Tighten all threaded joints.
(3) If soldering to the inlet and outlet tubes, observe
Step 6a above.
c. CPVC PLASTIC PIPE
(1) Clean, prime and cement all joints, following the
manufacturer's instructions supplied with the plastic
pipe and fittings.
(2) If soldering to the inlet and outlet tubes, observe
step 6a above.
7. COLD WATER PIPE GROUNDING
The house cold water pipe (metal only) is often used as
a ground for the house electrical system. The 3-valve
bypass type of installation, shown in Figure 1, will main-
tain ground continuity. If you use the plastic bypass,
continuity is broken. To restore the ground, do either
step 7a or 7b following.
a. Use the included ground clamp kit (included) to make
a jumper across the inlet and outlet copper tubes (See
Figure 4A).
b. Install a #4 copper wire across the removed section
of main water pipe, securely clamping at both ends
(See Figure 4B) – parts not included.
8. INSTALL VALVE DRAIN HOSE
NOTE: See valve drain options on Page 4.
a. Elevating the drain hose may cause back pressure
that could reduce the brine draw during recharge. If
raising the drain line overhead is required to get to the
drain point, measure the inlet water pressure to the sof-
tener first. For inlet pressures between 20 and 50 psi,
do not raise higher than 8 feet above the floor. For inlet
pressure above 50 psi, the drain line may be raised to a
maximum height of 14 feet.
b. Connect a length of 1/2" I.D. hose (check codes) to
the valve drain elbow, on the controller. Use a hose
clamp to hold the hose in place. Route the hose out
through the notch in the back of the top cover.
c. Run the hose to the floor drain, and as typically
shown in Figure 1, tie or wire the end to a brick or other
heavy object. This will prevent “whipping” during
recharges. Be sure to provide a 1-1/2" minimum air
gap, to prevent possible sewer water backup.

9. INSTALL BRINE TANK OVERFLOW HOSE
a. Connect a length of 1/2" I. D. hose to the brine tank
overflow elbow and secure in place with a hose clamp.
b. Run the hose to the floor drain, or other suitable
drain point no higher than the drain fitting on the
tank. If the tank overfills with water, the excess water
flows to the drain point.
10. On Two-tank models,
connect the brine tub-
ing to the nozzle and venturi housing.
